年产120万吨冷轧带钢车间设计 毕业设计.doc

摘要根据任务书要求，设计年产12万吨冷轧带钢车间设计。 按照车间设计的步骤，主要完成建厂经济依据论述、产品大纲制定、轧机比较及布置选择、压下分配、轧制规程计算、轧制图表、年产量计算、轧制力计算、轧辊强度校核、电机发热校核、凸度规程计算，原始轧辊辊型设定、辅助设备的选择及金属平衡、燃料消耗计算。 设计中参阅了国内外有关轧机的先进工艺、轧机的装备、技术及一些辅助设备的论述，特别参考了唐钢冷轧薄板厂生产线参数和现场数据，使本设计车间达到工艺合理、设备先进、为以后生产优质平直深冲汽车板创造条件。 本设计车间能生产的带钢品种多，规格齐全。产品规格为0.15～mm冷轧板，典型产品为mm彩涂基板。 设计附有车间平面图。 关键词：1700冷轧；车间设计；CVC轧机；HC轧机； ABSTRACT According to the task requirements, I designed this cold-rolling workshop for an annual output of 1.2 million tons.  Steps in accordance with the workshop design,I mainly complete the building of economy, the product outline of the development, comparison and mill layout options, press distribution, the calculation of order rolling, rolling chart, annual terms, the calculation of rolling force and roll strength , the electrical heat check, crown of order, the original roll-type settings, the choice of auxiliary equipment and the calculation of fuel consumption. Refer to the design of domestic and foreign advanced technology of the rolling mill, rolling mill equipment, technology and some discussion of auxiliary equipment, especially reference to the Tangshan Iron and Steel cold-rolled sheet production line parameters ,making the design process to achieve a reasonable workshop, advanced equipment, and making rooms for creating automobile panels. The steel plant can produce more complete specifications.The product specifications range 0.15 to 1.2mm and the typical product is the thickness of 0.5mm. There is a picture of the plan following the design workshop. Key words: 1700cold-rolling; workshop design;CVC milling roll;HC milling roll;目次 摘要 I ABSTRACT II 引 言 1 文献综述 2 第1章 建厂依据和产品大纲 5 1.1 建厂依据 5 第2章 轧钢机类型和布置形式比较选择 7 2.1 连轧机形式选择 7 2.2 轧机的选择 8 第3章 压下规程设计 13 3.1确定压下规程 13 3.2 确定轧机速度制度 16 3.2.1 轧制速度的确定 16 3.2.2 轧辊转速的确定 17 3.2.3 加速度的选择 18 第4章 力能参数的计算及空载辊缝的设定 19 4.1 轧制压力的计算 19 4.2 轧制力矩的确定 24 4.2.1 轧制力矩的确定 24 4.2.2 摩擦力矩的确定 25 4.2.3 空转力矩的确定 25 4.3 各机架空载辊缝值的设定 26 第5章 电机能力验算 29 第6章 轧辊强度校核 31 6.1 综述 31 6.2 确定工作辊和支撑辊的各个重要尺寸 32 6.3 轧
